Tru-Stone and simulated-stone pen blanks give you the dramatic look of turquoise, malachite, lapis lazuli, granite, and other natural stone without the cost, weight, or turning difficulty of real stone. They machine on a wood lathe like a dense resin, hold edges crisply, and polish to a stone-like luster. The visual depth is remarkable — most people who pick up a finished Tru-Stone pen are convinced they're holding actual stone. Pair them with antique platings (copper, brass, or pewter) for a pen that looks like it came out of a museum case.
